Abstract

PURPOSE: To enable suitable feeding, by constituting to have three feeding speeds in addition to the feeding speed at reproducing mode and to select one speed according to the operating mode of a reproduction device.
CONSTITUTION: Two signals indicating the mode of feeding are fed to the analog switch 62, the voltage input from each slider of variable resistors VR1, VR2, VR3 is selected and converted and output to the noninverting amplifier 63. The voltage fed from the variable resistors VR1WVR3 makes the rotating speed of the motor 25 to high, medium and low speed. For example, when the pickup 12 is moved from the waiting position to the program signal start position of a disc, the switch 62 outputs a voltage from VR1 with the control signal. The output signal from the noninverting amplifier 63 is selected with the switch circuits 64, 65 and it is fed to the motor 25 through the amplifier 66 and the drive circuit 67, and one of three speeds is selected according to the operating mode of the reproduction device for control. With the constitution like this, suitable feeding is made.
